Hourglass dispersion in overdoped single-layered manganites
H. Ulbrich, P. Steffens, D. Lamago +2
The excitation spectrum in single-layered Nd(0.33)Sr(1.67)MnO4 and Pr(0.33)Ca(1.67)MnO4 resembles the hourglass-like excitation dispersion seen in various cuprates superconductors.…

Incommensurate magnetic excitations in superconducting LiFeAs
N. Qureshi, P. Steffens, Y. Drees +8
Magnetic correlations in superconducting LiFeAs were studied by elastic and by inelastic neutron scattering experiments. There is no indication for static magnetic ordering but ine…
